Description

[0001] The present invention relates to a device carrier for attaching an electrical component to a support profile of a luminaire support rail system extending longitudinally along a longitudinal axis with a defined cross-sectional contour, as well as to a luminaire support rail system equipped with this device carrier.

[0002] Luminaire support rail systems of the type mentioned above are generally known from the prior art, such as the applicant's TECTON system. Such luminaire support rail systems make it possible to create lighting systems of any length and branching, in particular strip lighting. At least one or more elongated support profiles are provided; the latter can be arranged in series or branched from one another in any desired manner. The support profiles generally comprise an elongated profile element with an elongated receiving opening, to which functional elements can be mechanically and electrically coupled. Such functional elements include, for example, electrical components such as bar lights, spotlights, loudspeakers, sensors, and the like. Sections of the receiving opening not occupied by an electrical component can be covered, for example, with a blank cover.

[0003] To increase the flexibility and functionality of such a luminaire support rail system, additional electrical components can be provided that are arranged outside the support profile. These electrical components are usually attached and electrically connected to the rear of the support profile (e.g., on the side facing away from the receiving opening). Electrical components located there can sometimes be limited in their functionality if they are at least partially concealed by the support profile itself in a frequently desired functional direction - particularly downwards. To increase the functional range, the electrical component can be movably attached to the rear, for example, using complex and space-consuming movement mechanisms. It is also conceivable to provide a mechanical cantilever beam to which the electrical component is attached in such a way that its functional range is not restricted.This often leads to an aesthetically disadvantageous appearance and an undesirable shift in the center of gravity of the entire system.

[0004] It is therefore an object of the present invention to provide a simple way of attaching an electrical component to a corresponding luminaire support rail system while at the same time providing a good functional range.

[0005] This object is achieved by the subject matter of the independent claims. The dependent claims develop the central idea of ​​the present invention in a particularly advantageous manner.

[0006] According to a first aspect, the present invention relates to a device carrier for attaching an electrical component to a support profile of a luminaire support rail system, said support profile extending elongately along a longitudinal axis with a defined cross-sectional contour. The device carrier comprises, on the one hand, a base body. The base body, in turn, comprises a housing section for receiving at least part of the electrical component. Furthermore, the base body comprises a receiving section for the axial passage and for the radial form-fitting reception of the support profile. Unless otherwise stated, the terms "radial" and "axial" generally refer to the longitudinal axis of the support profile to be received or, more generally, represent a relative relationship between the components and sections in question; axial and radial are therefore essentially perpendicular to one another.The receiving section extends axially through the housing section as a through-opening with a defined cross-sectional contour ("defined" in this context therefore preferably means with a cross-sectional contour that is essentially unchanged in shape and dimension, viewed axially and extending along its length). The device carrier further comprises a cover. The cover can be placed onto the base body in a radial placement direction such that the cover covers the base body on the side of a radial opening of the receiving section. The (placed) cover and the housing section together delimit a receiving space for accommodating at least part of the electrical component.The device carrier further comprises an electrical contact element which, when the cover is in place - i.e. on the cover side - extends from the receiving space over the radial opening into the receiving section, so that an electrical contact part of the electrical contact element can protrude into the receiving space when the support profile is received in the receiving space and can be electrically connected there.

[0007] The device carrier is therefore designed such that the base body and the cover can be arranged together around the support profile. The receiving space thus provided makes it possible to easily position the electrical component at any point around the support profile. By means of the electrical contact element, an electrical tap can be easily made via the radial opening via the support profile which is received (on the side) on the circumference. The electrical tap can thus be produced effectively, safely and easily. In addition, the simple but effective design allows an electrical component to be provided quickly and safely at any point on the support profile of a luminaire support rail system. Since the housing section and the cover delimit the receiving space, at least part of the electrical component can be securely provided and received therein.

[0008] The electrical contact element can preferably be rotatable—or arranged so as to be rotatable—about a radially extending axis of rotation relative to the base body. This makes it possible, for example, to move the contact element into a defined contacting position for effective electrical contacting or, for example, to mechanically secure the contact element relative to the base body.

[0009] The electrical contact part can preferably extend outwards transversely – i.e., for example, radially – to the axis of rotation in order to move around the axis of rotation when the contact element rotates. A contact part projected laterally in this way can thus be effectively rotated into a contacting position. It is conceivable, for example, that the contact part can be brought into electrical contact with an electrical contact element on the side of a support profile accommodated in the device carrier by rotation. Such an electrical contact element of the support profile can, for example, be in the form of an elongated electrical conductor, which can, for example, be part of a busbar running axially in the support profile.

[0010] The device carrier can preferably further comprise a stop section. This is then provided in such a way that it moves together with the electrical contact element when the electrical contact element rotates about the axis of rotation. For this purpose, the stop section can be connected to the contact element directly or indirectly (e.g. via the cover). The stop section can preferably be arranged in such a way that it limits the angle of rotation of the electrical contact element about the axis of rotation. For this purpose, for example, the stop section can protrude into the receiving section in order to collide with the support profile at a corresponding rotational position and in the process limit the angle of rotation. The stop section can also be positioned in such a way that it collides with a corresponding stop section of the device carrier - e.g. the base body or its housing section - which lies in the travel path of the stop section, at a corresponding ordesired rotational position. In this way, the rotational movement of the electrical contact element around the rotational axis can be defined and limited in one or both opposite directions. For example, contacting and release positions can be approached in a defined manner; the user also receives feedback when the desired position is reached. This also prevents, for example, over-tightening of any cables connected to the electrical contact element.

[0011] The electrical contact element can preferably be attached to the cover; this can particularly preferably be movable or immovable. In this way, handling of the contact element can be simplified in that it can be handled with the cover. It can also be made possible to position the electrical contact element in a defined manner by placing the cover on top, thus simplifying assembly. If the electrical contact element is attached to the cover in a movable manner, it can be attached to the cover so that it can rotate about its axis of rotation, for example. This means that, with the cover firmly in place, the electrical contact element can be optionally moved / rotated into a defined electrical contacting position. The electrical contact element can also be attached to the cover so that it can move along its axis of rotation, for example in order to set the electrical contact part to different contact levels.If the electrical contact element is fixedly attached to the cover, the electrical contact element can be easily handled by means of the cover and preferably also rotated about its axis of rotation by means of the cover.

[0012] The electrical contact element can preferably be fixedly connected to the cover at least along the attachment direction or axially with respect to the axis of rotation, and preferably also around the axis of rotation. In the former case, for example, the electrical contact element can be handled together with the cover, while still being able to rotate relative to the cover about its axis of rotation. In this way, for example, the cover can be fixedly mounted, while an electrical connection can still be selectively established via the relative rotatability of the electrical contact element. If the cover and the contact element are fixedly connected to one another, assembly and electrical connection can be simplified, for example, by simply placing the cover on top.It may also be conceivable, as will be described below, that in such a configuration the cover is provided so as to be rotatable, so that the rotational movement of the contact element about its axis of rotation is carried out via the cover, so that electrical contact is made particularly simple and safe.

[0013] The electrical contact element can preferably be designed such that the electrical contact part can be arranged or adjusted in different positions along the mounting direction or axially with respect to the rotation axis. This makes it possible to provide the contact part in different positions as required, for example, in contact planes offset (parallel) from one another. The contact element can thus be adjusted according to the contacting requirements of the luminaire support rail system. This is particularly advantageous if a busbar with different contact planes is provided on the support profile side for electrical tapping.

[0014] The electrical contact element can preferably have a plurality of electrical contact parts arranged distributed along the mounting direction or axially with respect to the rotation axis. In this way, the electrical contact element can simultaneously tap from several contact levels on the support profile side. This is particularly advantageous if a busbar with different tap levels is provided on the support profile side. Such an electrical contact element can also make it possible to accommodate various support profiles, each with a different tap level, while always reliably establishing electrical contact and thus an electrical tap.

[0015] In principle, the features of a different positioning or adjustment of the contact part on the one hand and the contact parts arranged in different levels on the other hand can be combined as desired.

[0016] The cover, on the one hand, and the housing section, on the other hand, can preferably have corresponding coupling sections, so that the cover, when attached to the base body—i.e., in the attachment direction—can be supported in a defined radial position on the base body. The coupling sections can thus provide the operator with feedback regarding the correct positioning of the cover relative to the base body. If the cover is provided connected to the electrical contact element, the contact part can also be correctly positioned effectively in this way.

[0017] The coupling sections can preferably each have corresponding locking sections to secure the cover in the attached state in the defined radial position on the base body—preferably releasably. In this way, the attached cover can be securely held in its operating position. This can alternatively or additionally be achieved by the electrical contact element connected to or attached to the cover simultaneously establishing a mechanical coupling when the electrical contact is created, which then also holds the cover in its attached position. The locking sections can be designed, for example, as a snap closure, screw closure, bayonet closure, or the like.

[0018] The coupling section of the cover can preferably extend laterally beyond or encompass the coupling section of the housing section with respect to the mounting direction. This allows the operator to safely check the position of the cover. It also prevents the housing section from drifting sideways and thus preventing the positive connection between the base body and a support profile from accidentally becoming loose. This also provides effective fall protection.

[0019] The coupling sections can preferably be designed in such a way as to rotate the cover relative to the base body about a radially extending axis of rotation. In this way, for example, a positive connection between the cover and the base body can be achieved if, for example, the coupling sections have the above-described locking sections in the form of a screw cap or a bayonet catch. It can also be made possible, for example, if the cover is fixedly connected to the electrical contact element, for an electrical connection of the electrical contact element or its electrical contact part to be established via the cover by means of the rotational movement of the cover. It is also conceivable that, for example, a desired orientation of these components relative to one another can be achieved or maintained in a simple manner by means of the corresponding rotational movement of the cover relative to the base body.adjusted or the cover can be arranged in different rotational angle positions relative to the base body, each of which is advantageous for a different operating function. For example, by rotating the cover in different positions relative to the base body, access from the outside via the cover into the receiving space can be optionally opened or closed. In the former case, this can make it possible to run external cabling into the device carrier. In the latter case, the device carrier can be set up for self-sufficient operation - e.g. when using a battery-operated electrical component - and thus be safely separated from the outside (e.g. to achieve a desired IP protection class).

[0020] The housing section can preferably have coupling projections directed towards one another in the region of the radial opening, viewed in the axial direction, for the form-fitting and preferably latching fastening of the base body to a support profile received in the receiving section. The coupling projections delimit the radial opening on both sides. This makes it possible to provide a secure connection between the device carrier and the support profile guided thereby in an effective and compact manner. Snap-on coupling projections in particular enable the device carrier to be easily and flexibly positioned at any desired position on the support profile along its longitudinal axis. In order to prevent the coupling projections from undesirably wandering out when the device carrier is fastened - i.e. when the support profile is received - the coupling sections described above can be provided, wherein the coupling section of the cover preferably delimits the coupling section of the base carrier with regard tothe direction of attachment encompasses the outside on the side.

[0021] The device carrier can preferably further comprise the electrical component, which is more preferably at least partially accommodated in the receiving space. Thus, the device carrier can be easily provided with a defined function. In principle, it is conceivable for the device carrier to be optionally equipped with different types of electrical components, so that, for example, a customer can equip the device carrier with one or more desired functions accordingly, further increasing the flexibility of the device carrier.

[0022] The electrical component can preferably have a functional section. This can be, for example, a light-emitting section or a lamp of a luminaire, a detector of a sensor, the sound generation unit of a loudspeaker, and the like. The electrical component can thus be a luminaire (e.g., a surface-mounted luminaire, a pendant luminaire, a spotlight, etc.), a sensor unit (e.g., a light sensor, a motion sensor, a presence sensor, etc.), a loudspeaker, a camera unit, and the like. The functional section can be provided effectively and simply using the device carrier.

[0023] The functional section can preferably be arranged in a receiving area. The receiving area can preferably form part of the receiving space, so that the device carrier as a whole is particularly compact and easy to handle. Alternatively or additionally, it is also conceivable for the receiving area to be arranged outside the base body and preferably connected to the housing section - e.g. movably or immovably. The functional section can thus be provided in a simple manner and with any desired exposure. Since the receiving space is designed such that it essentially surrounds the support profile to be received therein on the side and circumference, the functional section can thus be provided in a particularly flexible and simple, as well as compact, manner at any desired position around the longitudinal axis of the support profile.

[0024] The receiving area can preferably be arranged opposite the receiving section of the radial opening. This allows the functional section to be provided in a position independent of the lid. As a result, the functional section does not interfere with the handling of the lid. Furthermore, the functional section can be provided, for example, on the front side of a support profile guided by it, thus making it highly effective.

[0025] The electrical component can preferably have a wiring that is (electrically) connected or connectable to the electrical contact element. In this way, the electrical component or its functional section can be easily electrically connected to the contact element, even if they are provided at a distance from one another; for example, in different areas of the receiving space or even with the functional section arranged outside the base body.

[0026] The wiring can preferably have a plug connection for selectively connecting or disconnecting a component-side wiring section and a contact element-side wiring section. Thus, a corresponding electrical connection can be easily established if, for example, the electrical component and the base body are provided as separate parts. This also allows the electrical component to be replaced without replacing the electrical contact element, for example, for maintenance purposes or to provide a different type of electrical component.

[0027] The device carrier, preferably at least the housing section or the base body and / or the cover, can have a substantially round and preferably circular outer contour, preferably viewed in the attachment direction. This allows for an aesthetically pleasing appearance. A round outer contour of the housing section can also provide a correspondingly compact but effectively usable receiving space, for example due to the outwardly curved side walls. A correspondingly round outer contour of the cover enables easy handling and attachment of the same to the base body. Furthermore, the cover, if it is to be provided so that it can rotate about one of the axes of rotation, can be easily provided so that it can rotate accordingly.

[0028] According to a further aspect, the present invention further relates to a luminaire support rail system. This comprises, on the one hand, a support profile which extends elongately along a longitudinal axis with a defined cross-sectional contour and which delimits a connection space. Furthermore, the luminaire support rail system comprises a device carrier according to the present invention, as already described above. The support profile is or can be passed axially through the receiving section and can thus be received or accommodated therein in a radially form-fitting manner. The cover can then be or is placed accordingly on the base body. The electrical contact element can protrude into the connection space with its electrical contact part or protrudes into it and is or can be electrically connected therein.

[0029] The advantages previously described for the device carrier can thus be transferred to the luminaire support rail system.

[0030] An axially extending busbar, to which the electrical contact element can be electrically connected, can preferably be arranged in the connection compartment. This allows the device carrier or its electrical contact element, and thus preferably also its electrical component, to be electrically connected in a particularly simple manner.

[0031] The busbar can preferably be arranged such that the electrical connection to the electrical contact element can be selectively established or broken by rotating the electrical contact element or the cover fixedly connected to it around a rotational axis extending radially—preferably radially to the support profile or its longitudinal axis—and thus by moving the electrical contact part, which extends outward transversely to this rotational axis, around the rotational axis. In this way, the electrical connection can be established particularly easily, intuitively, and thus effectively.

[0032] The support profile can preferably comprise an elongated profile element and a preferably elongated functional element connected to it. Thus, the device carrier can be effectively and flexibly arranged at any location within the luminaire support rail system, even in the area of ​​a functional element. The functional element, like the profile element, is preferably guided through the receiving space, thus receiving the support profile in a radially positive-locking manner within the receiving space.

[0033] When a support profile is accommodated in the receiving space, the functional element can preferably be arranged on a side of the profile element opposite the radial opening of the receiving section. In this way, the cover, on the one hand, and the electrical contact element, on the other hand, can be provided on the rear side of the support profile. This enables effective electrical coupling via the electrical contact element, while simultaneously creating an appealing aesthetic appearance. Furthermore, for example, a functional section of an electrical component of the device carrier can be effectively arranged on a front side or a lateral side of the support profile in order to optimally provide its function.

[0034] The cross-sectional contour of the support profile preferably corresponds substantially to the cross-sectional contour of the receiving section, and these are particularly preferably identical. This ensures a high degree of precision fit between the device carrier and the support profile, allowing the device carrier to be positioned and secured particularly securely.

[0036] The figures show different views of a device carrier 1 according to the invention and of a luminaire support rail system 100 equipped therewith. The device carrier 1 is first described below.

[0037] The device carrier 1 is basically used to attach an electrical component 2 to a support profile 110 of the luminaire support rail system 100, which extends longitudinally along a longitudinal axis L with a defined cross-sectional contour C.

[0038] The device carrier 1 has a base body 3, which is basically the same as in all figures except the Fig. 6. The base body 3 in turn has a housing section 4 for receiving at least a part of the electrical component 2, as shown schematically, for example, in the Fig. 4. The housing section 4 can preferably be made of a plastic; for example, using a plastic injection molding process.

[0039] The base body 3 has or further forms a receiving section 5 for axially passing through and radially positively receiving the support profile 110, as is particularly the case with Fig. 1-5, 7, and 8. The receiving section 5 extends axially through the housing section 4 as a passage opening with a defined cross-sectional contour Q. Thus, the receiving section 5 is at least partially circumferentially delimited by the housing section 4 to form the passage opening.

[0040] The device carrier 1 further comprises a cover 6. The cover 6 can be made of a plastic material, for example, by means of a plastic injection molding process.

[0041] The cover 6 can be placed on the base body 3 in a radial placement direction A such that the cover 6 covers the base body 3 on the side of a radial opening 7 of the receiving section 5, as is shown in all figures and in particular in the sectional views of the Fig. 3 and Fig. 4 can be seen.

[0042] The cover 6 and the housing section 4 together define a receiving space 8 for receiving at least a part of the electrical component 2, as can be seen in particular from the sectional views of the Fig. 3-5 can be seen.

[0043] As in particular the Fig. 6-14, the device carrier 1 and preferably at least the housing section 4 and / or the cover 6, viewed in the mounting direction A, can have a substantially round or circular outer contour.

[0044] The cover 6 on the one hand and the housing section 4 on the other hand can preferably have mutually corresponding coupling sections 60, 40, so that the cover 6 in the mounted state towards the base body 3 - i.e. in the mounting direction A - is carried in a defined radial position on the base body 3, as can be seen in particular from the sectional views of the Fig. 3-5 can be seen.

[0045] The coupling sections 60, 40 can preferably each have corresponding locking sections 61, 41 to secure the cover 6 in the attached state in the defined radial position on the base body 3—for example, releasably. These locking sections 61, 41 can, for example, be corresponding elements for forming a snap closure, a screw closure, or a bayonet closure.

[0046] The coupling section 60 of the cover 6 can preferably encompass the coupling section 40 of the housing section 4 laterally on the outside with respect to the mounting direction A, as can also be seen in particular from the sectional views of the Fig. 3-5 can be seen.

[0047] As can also be seen from the aforementioned sectional views, the coupling sections 60, 40 can preferably be designed in such a way as to rotate the cover 6 relative to the base body 3 about a radially extending axis of rotation Y.

[0048] As can be seen particularly from the side views of the Fig. 1-5 but also the representation of the Fig. 8, the housing section 4 can have, viewed in the axial direction in the region of the radial opening 7, coupling projections 9 directed towards one another for the positive and preferably locking fastening of the base body 3 to a support profile 110 received in the receiving section 5, which delimit the radial opening 7 on both sides and thus preferably form an undercut towards the receiving space 8.

[0049] The device carrier 1 further comprises an electrical contact element 10. The electrical contact element 10 extends, when the cover 6 is in place, from the receiving space 8 via the radial opening 7 into the receiving section 5, so that an electrical contact part 11 of the electrical contact element 10 projects into the receiving space 8 when the support profile 110 is received in the receiving space 8 (cf., for example, the Fig. 1, Fig. 2, Fig. 4 and Fig. 5) and can be electrically connected there, as shown in the illustrations of the Fig. 1 and Fig. 5 is indicated.

[0050] The electrical contact element 10 can particularly preferably be rotatable or arranged to rotate about a radially extending axis of rotation X relative to the base body 3. The electrical contact part 11 can preferably extend outwards transversely - for example radially - to the axis of rotation X, as for example in the Fig. 1, Fig. 2 and Fig. 5, in order to move around the rotation axis X when the contact element 10 rotates around this rotation axis X. Thus, the electrical contact element 10 can, for example, be moved between a Fig. 1, Fig. 2 and Fig. 5 for electrical contact with the support profile on the one hand and a release or assembly position oriented, for example, perpendicular thereto - i.e., rotated by 90° around the rotation axis X. In the contacting position, the electrical contact parts 11 shown here are extended laterally and are in electrical contact with the support profile side. The electrical contact element 10 can thus also be used, for example, to fasten the cover 6. In the release or assembly position, the electrical contact parts 11 - here viewed in the axial direction of the support profile 110 or the receiving section 5 through the through opening - are retracted in order to easily enable the electrical contact element 10 to be inserted and removed from the receiving section 5 via the radial opening 7.

[0051] The device carrier 1 may preferably further comprise a stop section 12, as shown for example in the Fig. 3 is shown schematically. The stop section 12 is preferably provided in such a way that when the electrical contact element 10 rotates about the axis of rotation X, it moves together with the electrical contact element. The stop section 12 is preferably arranged in such a way that it can limit an angle of rotation of the electrical contact element 10 about the axis of rotation X. In the exemplary embodiment shown here, the stop section 12 is, for example, fixedly connected to the cover 6 or formed integrally with it. However, the stop section 12 can also be directly connected to or provided with the electrical contact element 10. By rotating the cover 6, which is connected here to the electrical contact element 10, the cover can be moved between two positions in which the stop section 12, for example,When the support profile 110 is inserted, it abuts the support profile 110 at the top and outside, respectively, and thus limits the rotational movement here, preferably in both directions. The stop section 12 can be provided such that it permits a rotational movement of the cover 6, for example, by 90°. Thus, for example, the cover 6 can be rotated such that it moves the electrical contact element 10, which rotates with it, optionally between the contacting position and the release or assembly position. The in . Fig. 3 The provision of the stop section 12 shown as an example can also serve as an orientation for correct placement of the cover 6, since if the cover 6 is incorrectly oriented it will rest on the support profile 110 at the top and thus cannot be placed on the base body 3.

[0052] The electrical contact element 10 can preferably be fastened to the cover 6, as already described above. In this case, the electrical contact element 10 can, for example, be immovably - i.e., fixedly - fastened to the cover 6. A rotational movement of the cover 6 about the axis of rotation X can thus be transmitted easily and directly to the electrical contact element 10. Furthermore, the electrical contact element 10 and the cover 6 can be handled together in this way. If the electrical contact element 10 and the cover 6 are movably fastened to one another, the electrical contact element 10 can, for example, be rotated relative to the cover 6 about the axis of rotation X, so that, regardless of the position of the cover 6, the electrical contact element 10 can, for example, be moved into its contacting position by rotating about the axis of rotation X.

[0053] The electrical contact element 10 can preferably be fixedly connected to the cover 6 at least along the mounting direction A or axially with respect to the rotation axis X, and preferably also around the rotation axis X. In the former case, the electrical contact element 10 can thus be rotated independently of the cover 6, for example, and thus selectively moved into its contacting position. In the latter case, the movement of the cover 6 can be easily transmitted to the electrical contact element 10, which simplifies electrical contacting and assembly.

[0054] As can be seen in particular from the Fig. 1 and Fig. As can be seen in Figure 2, the electrical contact element 10 can be designed such that the electrical contact part 11 can be arranged or adjusted in different positions (i.e., at different heights) along the mounting direction A or axially with respect to the rotation axis X. Thus, for example, different tapping heights for the electrical tapping can be set.

[0055] In principle, it is also conceivable that the electrical contact element 10 has a plurality of electrical contact parts 11 distributed along the mounting direction A or axially with respect to the rotation axis X; for example, a combination of the Fig. 1 and Fig. 2. In this way, different tapping levels can be provided simultaneously, for example to always enable electrical tapping on different support profiles 110 with different tapping heights or to enable electrical tapping on different tapping levels of the same support profile 110 at the same time.

[0056] As already mentioned, the device carrier 1 can further comprise the electrical component 2. This is then preferably at least partially accommodated in the receiving space 8, as shown, for example, in the schematic representation of the Fig. 4 can be seen.

[0057] The electrical component 2 can preferably have a functional section 13. This functional section 13 can be, for example, a light-emitting area (e.g., reflector, lens, etc.) or a light source of a lamp (cf. Fig. 9-11), a sound generating element of a loudspeaker (cf. Fig. 12), an optical element of a camera (cf. Fig. 13) or a detector of a sensor (cf. Fig. 14).

[0058] The functional section 13 can preferably be arranged in a receiving area 14, 15. The receiving area 14 can form part of the receiving space 8, as shown, for example, in the schematic representation of the Fig. 4. Alternatively or additionally, the receiving area 15 can also be arranged outside the base body 3. In this case, the receiving area 15 can preferably be movably or immovably connected to the housing section 4. In the Fig. 12-14, for example, such external receiving areas 15 are shown, which are immovably or fixedly connected to the housing section 4. In Fig. 9, for example, an external receiving area 15 is shown here in the form of a spotlight housing, which can be moved relative to the housing section 4 to adjust the light emission direction and is thus movably connected thereto.

[0059] Again Fig. 4, the receiving area 14, 15 can be arranged opposite the receiving section 5 of the radial opening 7; in the exemplary embodiment shown here, therefore, on a lower side of the device carrier 1 or of the luminaire support rail system 100 comprising the device carrier 1.

[0060] The electrical component 2 may preferably further comprise a wiring 16 which is or can be electrically connected to the electrical contact element 10, as is also shown in Fig. 4 is indicated.

[0061] Likewise with reference to Fig. 4, the wiring 16 may have a plug connection 17 to selectively connect or disconnect a component-side wiring section 18 and a contact element-side wiring section 19.

[0062] The cover 6 can have a cable feedthrough opening 62 to, if necessary, introduce an electrical connection 20 from outside the device carrier 1 into it or vice versa. In this way, for example, the electrical contact element 10 and / or the electrical component 2 can establish an external electrical connection; for example, with an external device box, which can be attached to the rear of the support profile 110. The cable feedthrough opening 62 can optionally be equipped with a grommet or sealing cover in order to seal the receiving space 8 from the outside as much as possible at this point.

[0063] The connection of the device carrier 1 according to the invention and a support profile 110 extending longitudinally along the longitudinal axis L with the defined cross-sectional contour C forms the luminaire support rail system 100 according to the invention, which in all figures - except Fig. 10 and Fig. 11 - is shown. The support profile 110 defines a connection space 111, as shown in particular in Fig. 7 and Fig. 8 shown but also from the Fig. 1-5 can be seen.

[0064] As can be seen in particular from the Fig. 9 and 12-14, the support profile 110 can be an elongated profile element 112 (see in particular also the Fig. 7 and Fig. 8). The elongated profile element 112 here has the connection space 111 of the support profile 110 or at least partially delimits it. The profile element 112 here has, as in particular Fig. 7 and Fig. 8, preferably has an elongated receiving opening 113 through which the connection space 111 is accessible.

[0065] In addition to the profile element 112, the support profile 110 may further comprise a preferably elongated functional element 114 connected thereto or to be connected thereto. In the luminaire support rail system 100 of the Fig. In figures 9 and 12-14, this functional element 114 is, for example, a bar light. Other functional elements 114, such as sensors or simple glare sections, are also conceivable.

[0066] The functional element 114 is preferably inserted or insertable at least partially through the receiving opening 113 into the connection space 111 and can be electrically connected or coupled there. The functional element 114 can, for example, be attached to the coupling profiles 115 of the profile element 112, which border the receiving opening 113 on both sides.

[0067] When the support profile 110 is accommodated in the receiving space 8, the functional element 114 is preferably arranged with respect to the profile element 112 on a side opposite the radial opening 7, as can be seen, for example, from the Fig. 9 and 12-14.

[0068] The support profile 110, as mentioned, is axially guided or can be guided through the receiving section 5 and is radially positively received or can be received therein. In the operating state, the cover 6 is then placed on the base body 3. The electrical contact element 10 can protrude with its electrical contact part 11 into the connection space 111 or protrudes into it, as is shown, for example, in the Fig. 1, Fig. 2, Fig. 4 and Fig. 5. There, i.e. in the connection space 111, the electrical contact element 10 or its electrical contact part 11 can be electrically connected as shown in the Fig. 1, Fig. 2 and Fig. 5 is indicated.

[0069] As can be seen in particular from the Fig. 1, Fig. 5 and Fig. 7, an axially extending busbar 116 can be arranged in the connection space 111, to which the electrical contact element 10 can be electrically connected, as can be seen, for example, from the Fig. 1 and Fig. 5. For this purpose, the busbar 116 preferably has electrical conductors 117 arranged in several levels, which can be connected to the electrical contact part 11 and thus electrically contacted. If the electrical contact part 11 can be arranged or adjusted in different positions along the mounting direction A or axially with respect to the rotation axis X, this can enable tapping at different levels of the busbar. If the electrical contact element 10 has several electrical contact elements 11 arranged distributed along the mounting direction A or axially with respect to the rotation axis X, the latter can enable tapping at several of the levels of the busbar 116 simultaneously.

[0070] The busbar 116 can preferably be arranged in such a way that the electrical connection with the electrical contact element 10 can be selectively established or separated by rotating the electrical contact element 10 or the cover 6 fixedly connected thereto about a radially extending axis of rotation X, Y and thus by moving the electrical contact part 11 extending outwards transversely to this axis of rotation X, Y around the axis of rotation X, Y, as is also apparent from the Fig. 1, Fig. 2 and Fig. 5 can be derived.

[0071] As for example from the Fig. 1-5, 7 and 8 and in particular from the Fig. 9 and 12-14, the cross-sectional contour C of the support profile 110 can substantially correspond to the cross-sectional contour Q of the receiving section 5, and these are preferably even identical.

[0072] The present invention is not limited to the embodiments described above, as long as it is encompassed by the subject matter of the following claims.
